AEROPLANE-FUSEIAGE.

Application filed April 22, 1918. Seflalll'o. 782,787.

This invention relates to an aeroplanefuselage constituted entirely bythe juxtaposition and cohesion, at crossed directions, of very thinslats of small width of wood, cardboard, paper or the like. The fuselageobtained in this way, while being very light,

is endowed with extraordinary rigidity and solidity.

A form ofconstruction of the object of the invention is representedbyway of example upon the annexed drawing which shows:

Figure 1 an elevation of a selage in course of construction; in thisfigure there is represented only a portion of the wooden slats which arebroken away to show the crossed directions of the different layers. Fig.2 is a plan view corresponding to Fig. 1. Fig. 3 is an end view from theleft of Fig. 1. Fig. 4 represents on a larger scale a longitudinal axialsection of the front part of the finished fuselage and in which therehas been placed the frame which supports the different propelling andcontrolling devices. Fig. 5 shows the end view of the apparatus afterfixing the frame and the engine being supposed removed Fig. 6 is a planview of the struction of the fuselage.

finished fuselage. p

The construction of thefuselage is efiected upon a mold or former Acomposed of several parts with a view toallowing removal when thefuselage is finished. In the example represented, this former iscomposed of a central part a of pyramidal shape upon which are fixed byany suitable means cheeks a a a and 0. These checks are provided withgrooves b to allow of accommodating the ribs 6 of the fuselage uponwhich are to be nailed the wooden slats c which form the fuselage body.The former ismounted preferably upon trunnions d which allow ofrevolving it around its axis during the con- First therefore thedifferent parts of the former are assembled, after which the ribs 11upon which the uprights e for the shrouds may even be fixed in advanceare placed in position in the grooves 11 of the cheeks a, a a a. Thenthe position of the openings to be formed in the fuselage is determined:the pilots manhole f, openings 9 for the accommodation of the rearempennage, etc. The wooden slats c are next aflixed, which operation iseffected 1n the following manner: .These slats are nalled one besideanother upon the ribs b,

in this way forming a first lager upon which i is applied and glued orafiixe a second layer at a crossed direction and if necessary a and afourth. This work is greatly facihtated by the fact that the former canbe revolved around its axis. Moreover it is advantageous to aflix thewooden slats under tensioif; for this purpose when the slat is soaked orcoated with glue and fixedto a 'rlbb at one end, an energetic pull isexerted upon the other end by means'of any suitable device, for exampleby fixing this end in a VISQQI' tongs and exerting a pull upon the tongsby means of a tackle. It is evident that care be taken not to place theslats where openings have to be arranged. -When the fastening of theslats-is completed, the former is taken apart and removed; the fuselagecan then be clothed externally and varnished. In' this way thereisobtained a monoblock or one-piece fuselage, which isvery strong and verylightand oifers very little resistance to the air.

g In a 'fuselage'of this kind, it would be very difficult to proceed tofit the difierent pro-' pelling and controlling devices'in, the interiorof the fuselage itself, as is'don'e usu-* 'ally in other apparatus.There 'is available indeed only a space of very limited dimen sions, sothat fitting would be'very long and troublesome to perform and moreoverdifli cult'to verify. The presentinvention has for object to avoid thesedisadvantages; it consists in mounting't-helwhole or a part of theapparatus intended for the propulsion and thelcontrol of the apparatusupon an independent frame which is then introduced into the fuselage andsecured upon the fuse-: lage by'means of any. suitable device. In thisway-the fitting may be carried on upon'a-n erecting table for example,which allows'of avoiding any loss of time. and lends .itself I readilyto verifications. flhe; ,frame upon which the different parts aremounted in this way, when secured in the interior of.

the fuselage, forms to some extent a partition or bulkhead in thefuselage and therebyincreases rigidity. This partitioning may even beused to conduct toward the rear of the apparatus the burnt gasesexhausted from the engine.

front with a bonnet m which incloses the engine. This bonnet has anopenin m in which is engaged the cap-shaped ub m with which the ropellerm 1s provided. The opening m 1s larger than the hub 121." so as to leavean annular space through which the air serving for the cooling of themotor can penetrate.

Fig. 6 is a plan view of the finished fuselage showing the sub-divisionof the fuselage to allow the evacuation of the cooling air and the burntgases. In this figure the frame A has been supposed to be rovided uponits faces with tight-fitting walls n (see also Fig. 5) extendinglongitudinally so as to isolate completely the pilots room fromthe'space which contains the engine. There are formed in this waychambers .or compartments M, which are bounded externally by the wallsof the fuselage, in free communication with the space inclosing theengine and extending on either side of the apparatus. By forming in theshell at the rear of the planes suitable openings 0 there areconstituted channels which allow the cooling air and the burnt gases toescape as indicated by the arrows w. The rear portion ofthe shell mighteven be used for the evacuation of'these gases which would in this.

way take place at the rear of the apparatus.

WVhat I claim and desire to secure by Letters Patent of the UnitedStates is 1. A monoblock fuselage or body for aeroplanes, comprising ahollow frame formed of a plurality of superposed layers lued together,each layer consisting of thin p ates,

the plates of one layer crossing the plates of another layer.

2. A monoblock fuselage or body for aeroplanes comprising a hollow bodyformed of a plurality of superposed la ers glued together each layerconsisting 0 thin and narrow juxtaposed plates, the plates of one layerextending in a different direction to aeroplane,

the plates of another layer, the frame being provided with apertures inits sides.

3. A monoblock fuselage or body for an comprising a hollow frame formedof superposed layers, each layer consistin of thin and narrow juxtaposedplates, the p ates of one layer crossing the plates of another layer,the frame being provided with an upright at one end, an o ening adjacentits other end and a man ole intermediate of its ends.

4. A monoblock fuselage or body for aeroplanes comprising a hollow frameopen at one end and formed of a plurality of superposed layers, eachconsistmg of thin plates. the plates of one layer crossing the plates ofanother layer, and a frame-work carrying the engine and itsappurtenances and extending into the hollow frame.

5. A monoblock fuselage or body for aeroplanes, comprising a hollowframe openat one end and formed of a plurality of superposed layers,each layer consisting of thin and narrow juxtaposed plates, a frame workcarrying an engine and its appurtenances and arranged in the frame, withthe engine outside thereof, and an apertured cover for th open end ofthe frame and inclosing the engine.

6. A monoblock fuselage or body for aeroplanes, comprising a hollowframeopen at.

one end and formed of a plurality of superposed layers, each layerconsisting of thin juxtaposed plates, a frame work carrying an engineand its appurtenances and arranged in the hollow frame with the engineoutside thereof, an apertured cover for the open end of the frame andinclosing the engine, and a propeller on the. engine shaft outside ofthe cover.

7. A monoblock fuselage or body for aeroplanes, comprising a hollowframe formed of a plurality of superposed layers, each layer consistingof thin juxtaposed plates, the frame being provided with apertures inits sides and. interior walls forming longi tudinal passages forcirculation ofair and burnt gases. v
